tools headers arm64: Sync arm64's cputype.h with the kernel sources

To get the changes in:

  c8fc442ba22ae0a7 ("arm64: Add AMPERE1 to the Spectre-BHB affected list")

That addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/arm64/include/asm/cputype.h' differs from latest version at 'arch/arm64/include/asm/cputype.h'
  diff -u tools/arch/arm64/include/asm/cputype.h arch/arm64/include/asm/cputype.h
